Output Circuit
Output “H” Voltage
Operation by Vref voltage
Voltage, which is applied to Vref, of which high output, 2VBE is applied to base A of the Q2 (power
transistor) and low voltage, Q2VBE is output as VOUT (H) by the Vref circuit.
VOUT = Vref+2VBE Q2VBE
Vref+0.7 (V)
Vref
Vref terminal required to connect to VS terminal for stable operation in case of no requirement of
VOUT control.
